Answer:
D
Explanation:
D is correct because an increase in temperature of the gas molecules causes an increase in the average kinetic energy of these gas molecules. It is practically like giving them more power to flow around. They thus try to leave the confines of the container and hence are less soluble
A is wrong. Most solids would become more soluble with temperature increase
B is wrong
C is wrong as a pressure increase would yield higher solubility
